title: [Presence of carbonic anhydrase in 2 fish of the Kerguelen archipelago, Channichthys rhinoceratus lacking hemoglobin, and Notothenia megellanica with a normal blood formulation].
abstract: An antarctic hemoglobin-free Fish, living in the Kerguelen archipelago, Channichthys rhinoceratus, is devoid of carbonic anhydrase in the blood but has a high content of this enzyme in the gills which appears to be twice that of another normal species living in the same area. Notothenia magellancia. This enzyme appears to play an important role in the osmoregulation of the Channichthyidae.
